Application filed September 15. 1913. Serial No. 789,770.

To all whom if; may concern Be it known that 1, P1200101: P. CooLEY, a citizen of the United States, and a resident of Peoria, in the county of Peoria and State of Illinois, have invented a new and useful Improvement in Stoves or Furnaces, of which the following is a specification.

This invention relates to a new and useful improvement in a stove or furnace, and has particular reference to a draft regulating means formed on the stove or furnace door.

The principal object of this invention is the provision of a structure for the above named purpose which is simple in construction and operation, and which regulates the draft with accuracy, the construction pro-' viding an opening in the door which serves as a draft opening, and also'to accommodate the shaker bar or grate.

Another object of this invention is the provision of a draft regulating means for a stove or furnrce door which is so arranged as to permit the shaking of the grate with a minimum exposure of the ash-pit, thereby reducing the spread of dust and ashes to minimum.

To the accomplishment of the foregoing and such other objects as may hereinafter appear, my invention consists inthe construction, combination and arrangement of parts hereinafter described and then sought to be defined in the appended claims, reference being had to the accompanying drawings forming a part of this application and which show for illustrative purposes, a preferred embodiment of my invention, it be ing understood however that various changes may be made in practice withinthe scope of the claims without digressing from my inventive idea.

In the drawings: Figure 1 represents a front elevation of a stove or furnace door constructed according to my invention; Fig. 2 is a horizontal section on line 22 of Fig. 1, looking in the direction of the arrow; Fig. 3 is a horizontal section on line 3-3 of Fig. 1, looking in the direction of the vertically extending elongated slot 3. The door, at the sides of the opening 2 is formed with the outstanding and circumscribing port ons or ribs 4. Similar outstanding portlons 5, extend vertically across the door, and are spaced relative to each other and to said slot. The vertical portions e of the outstanding portions or ribs 4 have the ten minal shoulders or flanges 6. The outside of these ribs or outstanding portions 4 and 5 are smooth, so that the slide or shutter 7 may have practically an air-tight fit there on. This slide 7 hasa rectangular body portlon 8, slightly larger than said opening 2 and adapted to rest on the outstanding portlons 0r ribs 4 inside of said shoulders or flanges 6, which form guideways for said slide or shutter. Saidslide or shutter also has the depending extension 9, which is positloned and slides on said outstanding portions or ribs 5, entirely covering said slot 3 when the slide or shutter is in its upper position, the edges 9 of said extension being reduced so that they are on the same plane as the edges of the body portion 8, the shoulders 10 formed by reducing the edges bearing against the inside of said outstanding portions or ribs 5 to provide a guiding means and a tight fit. The lower end of the depending extension is provided on its inner face with a raised portion 11, which rests on the smooth portion 12 be tween the outstanding portions or ribs 5.

Near the upper end of said depending extension 9 where it joins the body portion 8 of the slide or shutter, is providedthe lug or projection 13, which is tapered to lit the inclined walls 3 of said slot 8. This lug or projection 13 engages the ends of the slot 3, to limit the movement of the slide or shutter in either direction. An aperture 14 is formed in the depending portion 9 of said slide or shutter .and passes through said lug or pro jection 13. Mounted in this aperture is the pin or post 15, which also passes through a housing 16 having the cap or head 17 secured on the end thereof, and a spring 18 positioned in said housing about said pin or post, and bearing against the head thereof, as shown. The other end of said pin or post is upset over a washer or hearing member 19, which rests and slides on the raised portion 20 which is provided along the edges of said slot on the inside of the door or opening. 1

By means of this construction it is seen that the slide or shutter, due to the smooth contact surface, has an air-tight engagement with the door. It may be adjusted in any position, and due to the action of the spring 18 will remain in that position until moved again. The opening 2 is located so that the shaker bar may be actuated, as is well understood. When necessary to shake the grate, the slide or shutter is moved downwardly to a slight distance, exposing a minimum amount of the draft opening, thereby reducing the spread of the dust and ashes to the smallest amount possible. This is an advantageous feature. It is therefore seen that I have provided a draft regulator which is simple in construction, having the advantage of being air-tight and readily adjustable. It is constructed of the fewest possible parts.

What I claim is 1. The combination with a door having a draft opening, and a slot below said opening,

-said door also having outstanding portions or ribs circumscribing said opening and outstanding portions or ribs extending parallel to and adjacent said slot, a slide or shutter member having a portion conforming in shape to said opening and adapted-to engage said circumscribing outstanding portions or ribs, said slide or shutter having-a dependingextension adaptedto rest and slide on said last mentioned outstanding portions or ribs, and means for slidably securing said slide or shutter to said door.

2. The combination with a door having a draft opening, and a slot below said opening, said door also having outstanding portions or ribs circumscribing said opening and outstanding portions or ribs extending parallel to andadjacent said slot, a slide or shutter member having a portion conforming in shape to said opening and adapted to engage said circumscribing outstanding portions or ribs, said slide or shutter having a depend ing extension adapted to rest and slide on said last mentioned outstanding portions or ribs, a lug or projection formed on the inside of said depending extension and adapted to be positioned in said slot, a spring controlled member passing through said depending extension and lug or projection and having securing means on theinner end thereof, whereby said slide or shutter is slidably and frictionally held in positioin on said door. a 7

3. The combination with a door having a rectangular opening in theupper portion thereof and an elongated vertical slot below said opening, said door having outstanding portions or ribs circumscribing said opening,

the side outstanding portions or ribs being extended downwardly and having shoulders or flanges along the edges thereof, said door also having outstanding portions or ribs extending parallel to said slot, a slide or shutter having a body portion slightly larger than said opening but conforming in shape thereto and positioned thereover with its ends located within said shoulders or flanges and having its inner bearing edges resting on said outstanding portions or ribs, said slide or shutter having a depending extension adapted to cover said slot when the slide or shutter is in its upper position and having its edges reduced and bearing on said second mentioned outstanding portions or ribs, the shoulders formed by said reduced edges engaging the inside edges of said second mentioned outstanding portions or ribs, and means for slidably and frictionally securing the slide or shutter on said door.

4:. The combination with a door having a rectangular opening in the upper portion thereof and an elongated vertical slot below said opening, said door having outstanding portions or ribs circumscribing said opening, the side outstanding portions or ribs being extended downwardly and having shoulders or flanges along the edges thereof, said door also having outstanding portions or ribs extending parallel to said slot, a slide or shutter having a body portion slightly larger than said opening but conforming in shape thereto and positioned thereover with its ends located within said shoulders or flanges and having its inner bearing edges resting on said outstanding portions or ribs, said slide or shutter having a depending extension adapted to cover said slot when the slide or shutter is in its upper position and having its edges reduced and bearing on said second mentioned outstanding portions or ribs, the shoulders formed by said reduced edges engaging the inside edges of said second mentioned outstanding portions or ribs, and means for slidably and frictionally securing the slide or shutter on said door, said means including a stud or projection on the inside of said depending extension positioned in said slot, a pin or post passing through said depending extension and said lug or projection, a head on one end of said pin or post, a spring member about said pin or post and engaging said head to normally tend to hold it outward, and a bearing member secured to the other end of said pin or post which is on the inside of the door.
